NATO early warning surveillance aircraft will patrol the skies over alliance members Latvia and the Netherlands when President Bush visits the two countries later this week.

An alliance statement Wednesday, says NATO Airborne Early Warning and Control aircraft, commonly called AWACS, will monitor airspace over the two countries from Friday to Sunday at the request of their governments.

Mr. Bush is flying to the Latvian capital, Riga, Friday for talks on Saturday with the presidents of Estonia, Latvia and Lithuania. He then flies to the Netherlands, where he will meet with Dutch officials and mark the 60th anniversary of the end of World War II in Europe with a stop at an American military cemetery in Margraten.

President Bush then travels to Moscow for Monday's World War II observances in the Russian capital.
